Email piping not working for PHP script. Local delivery failed error

Question

In cPanel I have piped the following to my script:

alerts@XXX.com  to  |/home/XXX/public_html/client/inc/msg/mailReader.php

I get the following email returned:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

pipe to |/home/XXX/public_html/client/inc/msg/mailReader.php generated by alerts@XXX.com local delivery failed

The path to mailReader.php is definitely correct, as well as the path to PHP in the shebang in mailReader.php. Line 1 is:

#!/usr/local/lib/php -q<?php

Do you have any idea why it would return the "local delivery failed" error?

Answer 1

The directory was actually #!/usr/bin/php -q. I have 2 other directories that have the files for PHP but this isn't looking for the PHP directory, its looking for the compiled PHP file in bin called "php".
